Atomizer for a personal vaporizing unit

ABSTRACT

A personal vapor inhaling unit is disclosed. An electronic flameless vapor inhaler unit that may simulate a cigarette has a cavity that receives a cartridge in the distal end of the inhaler unit. The cartridge brings a substance to be vaporized in contact with a wick. When the unit is activated, and the user provides suction, the substance to be vaporized is drawn out of the cartridge, through the wick, and is atomized by the wick into a cavity containing a heating element. The heating element vaporizes the atomized substance. The vapors then continue to be pulled by the user through a mouthpiece and mouthpiece cover where they may be inhaled.

TECHNICAL FIELD

This invention relates to personal vapor inhaling units and moreparticularly to a wick structure for an atomizer/vaporizer of anelectronic flameless vapor inhaler unit that may simulate a cigarette ordeliver nicotine and other medications to the oral mucosa, pharyngealmucosa, tracheal, and pulmonary membranes.

BACKGROUND

An alternative to smoked tobacco products, such as cigarettes, cigars,or pipes is a personal vaporizer Inhaled doses of heated and atomizedflavor, which provides a physical sensation similar to smoking. However,because a personal vaporizer is typically electrically powered, notobacco, smoke, or combustion is usually involved in its operation. Forportability, and to simulate the physical characteristics of acigarette, cigar, or pipe, a personal vaporizer may be battery powered.In addition, a personal vaporizer may be loaded with a nicotine bearingsubstance and/or a medication bearing substance. The personal vaporizermay provide an inhaled dose of nicotine and/or medication by way of theheated and atomized substance. Thus, personal vaporizers may also beknown as electronic cigarettes, or e-cigarettes. Personal vaporizers maybe used to administer flavors, medicines, drugs, or substances that arevaporized and then inhaled.

This mouthpiece may alsocomprise silicone rubber, thermoplastic elastomer, organosilane, silverimpregnated polymer, silver impregnated thermoplastic elastomer, and/orpolymer. The mouthpiece may be removed from the personal vaporizer forwashing or replacement, without using a tool. The mouthpiece may beprovided in different colors. Designs or other patterns may be visibleon the outside of the mouthpiece.

In an embodiment, a personal vaporizer unit comprises a first conductivesurface configured to contact a first body part of a person holding thepersonal vaporizer unit, and a second conductive surface, conductivelyisolated from the first conductive surface, configured to contact asecond body part of the person. When the personal vaporizer unit detectsa change in conductivity between the first conductive surface and thesecond conductive surface, the vaporizer is activated to vaporize asubstance so that the vapors may be inhaled by the person holding thevaporizer unit. The first body part and the second body part may be alip or parts of a hand(s). The two conductive surfaces may also be usedto charge a battery contained in the personal vaporizer unit. The twoconductive surfaces may also form, or be part of, a connector that maybe used to output data stored in a memory.

In an embodiment, a personal vaporizer unit comprises a chamberconfigured to receive a cartridge. The cartridge may hold a substance tobe vaporized. The chamber may be configured at the distal end of thepersonal vaporizer unit. A user may inhale the vaporized substance atthe proximal end of the personal vaporizer unit. At least one spacebetween the exterior surface of the cartridge and an interior surface ofthe chamber may define a passage for air to be drawn from outside thepersonal vaporizer unit, near the distal end, through the personalvaporizer unit to be inhaled by the user along with the vaporizedsubstance. The personal vaporizer unit may also include a puncturingelement that breaks a seal on the cartridge to allow a substance in thecartridge to be vaporized. An end surface of the cartridge may betranslucent to diffuse light produced internally to the personalvaporizer unit. The translucent end may be etched or embossed withletters, symbols, or other indicia that are illuminated by the lightproduced internally to the personal vaporizer unit.

In an embodiment, a personal vaporizer unit comprises a first wickelement and a second wick element having a porous ceramic. The firstwick element is adapted to directly contact a liquid held in areservoir. The reservoir may be contained by a cartridge that isremovable from the personal vaporizer unit.

FIG. 10 is a perspective view of a mouthpiece cover of a personalvaporizer unit. FIG. 11 is a distal end view of the mouthpiece cover ofFIG. 10. FIG. 12 is a cross-section view of the mouthpiece cover alongthe cut line shown in FIG. 11. As can be seen in FIGS. 10-12, mouthpiececover 114 has an opening 114-1 that allows air and the vaporizedsubstance to be drawn through mouthpiece cover 114. Mouthpiece cover 114is configured for contact with the mouth of a person. In an embodiment,at least part of the mouthpiece cover has an antimicrobial surface. Thisantimicrobial surface of mouthpiece cover 114 may comprise, but is notlimited to: silicone rubber, thermoplastic elastomer, organosilane,silver impregnated polymer, silver impregnated thermoplastic elastomer,and/or polymer. Mouthpiece cover 114 is also configured to be removablefrom personal vaporizer unit 100 by a user without the use of tools.This allows mouthpiece cover 114 to be replaced and/or washed. In anembodiment, mouthpiece cover 114 may be held in place on personalvaporizer unit 100 by annular ridge 114-2 which interfaces with a grooveon mouthpiece 116 of personal vaporizer unit 100 to secure mouthpiececover 114 in place. In another embodiment, mouthpiece cover 114 may beheld in place on personal vaporizer unit 100 by a friction fit.

FIG. 13 is a perspective view of a mouthpiece of a personal vaporizerunit. FIG. 14 is a side view of the mouthpiece of FIG. 13. FIG. 15 is across-section view of the mouthpiece along the cut line shown in FIG.14. As can be seen in FIGS. 13-15, mouthpiece 116 has a passageway 116-1that allows air and the vaporized substance to be drawn throughmouthpiece 116. Mouthpiece 116 may comprise a conductive surface ormaterial configured to contact a first body part of a person holdingpersonal vaporizer unit 100. This first body part may be part of a hand,or at least one lip of the person holding personal vaporizer unit 100.In an embodiment, mouthpiece 116 has an annular groove 116-2 around anoutside surface. This groove is configured to receive annular ridge114-2. Thus, annular groove 116-2 helps secure mouthpiece cover 114 topersonal vaporizer unit 100.

FIG. 16 is a perspective view of a mouthpiece insulator of a personalvaporizer unit. FIG. 17 is a distal end view of the mouthpiece insulatorof FIG. 16. FIG. 18 is a side view of the mouthpiece insulator of FIG.16. FIG. 19 is a cross-section view of the mouthpiece insulator alongthe cut line shown in FIG. 18. As discussed previously, mouthpieceinsulator 112 is disposed between outer main shell 102 and mouthpiece116. As can be seen in FIGS. 16-18, mouthpiece insulator 112 has apassageway 112-1 that allows air and the vaporized substance to be drawnthrough mouthpiece insulator 112. Because mouthpiece insulator 112 isdisposed between outer main shell 102 and mouthpiece 116, mouthpieceinsulator 112 can electrically isolate outer main shell 102 andmouthpiece 116. Thus, in an embodiment, mouthpiece insulator 112comprises, or is made of, a non-electrically conductive material. Thiselectrical isolation between outer main shell 102 and mouthpiece 116allow electrical impedance changes between outer main shell 102 andmouthpiece 116 to be detected.

For example, a first conductive surface on mouthpiece 116 may beconfigured to contact a first body part of a person holding personalvaporizer unit 100. A second conductive surface on outer main shell 102(which is conductively isolated from said first conductive surface bymouthpiece insulator 112) may be configured to contact a second bodypart of the person. Personal vaporizer unit 100 may then activate inresponse to detecting a change in conductivity between the firstconductive surface and the second conductive surface. In an embodiment,this change in conductivity may comprise a drop in impedance between thefirst conductive surface and the second conductive surface. In anembodiment, the change in conductivity may comprise a change incapacitance between the first conductive surface and the secondconductive surface. The first body part may be a finger. The second bodypart may be a lip. The second body part may be a second finger. In anembodiment, the first conductive surface and the second conductivesurface may be used to pass a charging current to battery 104. The firstand second conductive surfaces may also be used to transfer data to orfrom personal vaporizer unit 100.

FIG. 20 is a perspective view of a main housing of a personal vaporizerunit. FIG. 21 is a distal end view of the main housing of FIG. 20. FIG.22 is a proximal end view of the main housing of FIG. 20.

Mainhousing 160 is configured to hold PC-boards 123 and 124, and spacer 128.Main housing 160 is configured to fit within outer main shell 102 via afriction fit. Main housing 160 has several holes 166 that allow lightgenerated by a light source(s) on PC-board 124 to pass. Once this lightpasses through holes 166, it may be coupled into light pipe sleeve 140where it is conducted to a visible location on the outside of personalvaporizer unit 100.

Main housing 160 also has a hole 165 that allows an electrical conductor(not shown) to run from PC-board 123 or PC-board 124 through mainhousing 160. This electrical conductor may be, or connect to, a heatingelement (not shown). This heating element may help vaporize thesubstance to be inhaled by the user of personal vaporizer unit 100. Thisheating element may be controlled by circuitry on PC-board 123 orPC-board 124. This heating element may be activated in response to achange in conductivity between the first conductive surface and thesecond conductive surface, described previously.

The exterior of main housing 160 may also have a flat surface 164 (orother geometry) forming a galley that is configured to allow thevaporized substance and air to pass between the main housing 160 and theouter main shell 102. Once the vaporized substance and air pass by mainhousing 160, they may travel through passageway 112-1, passageway 116-1,and opening 114-1 to be inhaled by a user of personal vaporizer unit100. The exterior of main housing 160 may also have one or morestandoffs 167 (or other geometries) that are configured to allow air andthe vaporized substance to reach the passageway formed by flat surface164 and outer main shell 102.

FIG. 27 is a distal end view of themain housing of FIG. 25. FIG. 28 is a proximal end view of the mainhousing of FIG. 25. FIG. 29 is a side view of the main housing of FIG.25. FIG. 30 is a cross-section view of the main housing along the cutline shown in FIG. 29. Main housing 260 may be used as an alternativeembodiment to main housing 160.

Main housing 260 is configured to hold PC-boards 123 and 124, and spacer128. Main housing 260 is configured to fit within outer main shell 102via a friction fit. Main housing 260 has several holes 266 that allowlight generated by a light source(s) on PC-board 124 to pass. Once thislight passes through holes 266, it may be coupled into light pipe sleeve140 where it is conducted to a visible location on the outside ofpersonal vaporizer unit 100.

Main housing 260 also has a hole 265 that allows an electrical conductor(not shown) to run from PC-board 123 or PC-board 124 through mainhousing 260. This electrical conductor may be, or connect to, a heatingelement (not shown). This heating element may help vaporize thesubstance to be inhaled by the user of personal vaporizer unit 100. Thisheating element may be controlled by circuitry on PC-board 123 orPC-board 124. This heating element may be activated in response to achange in conductivity between the first conductive surface and thesecond conductive surface, described previously.

The exterior of main housing 260 may also have flat surfaces 264 (orother geometry) that form a galley that is configured to allow thevaporized substance and air to pass between the main housing 260 and theouter main shell 102. Once the vaporized substance and air pass by mainhousing 260, they may travel through passageway 112-1, passageway 116-1,and opening 114-1 to be inhaled by a user of personal vaporizer unit100. The exterior of main housing 260 may also have one or morestandoffs 267 (or other geometries) that are configured to allow air andthe vaporized substance to reach the passageway formed by flat surfaces264 and outer main shell 102.

FIG. 31 is a perspective view of a printed circuit board assembly of apersonal vaporizer unit. FIG. 32 is a distal end view of the PCBassembly of FIG. 31. FIG. 33 is a perspective exploded view of the PCBassembly of FIG. 31. FIG. 34 is a side exploded view of the PCB assemblyof FIG. 31. As can be seen in FIGS. 31-34, the PCB assembly is comprisedof PC-board 123 and PC-board 124 separated by a spacer 128. PC-board 124may have mounted upon it light emitting diodes (LEDs) 125-127 or otherlight sources. LEDs 125-127 are configured and positioned such that whenthey produce light, that light passes through holes 166 or 266 in mainhousings 160 and 260, respectively. This light may then be conducted bylight pipe sleeve 140 to a location where it will be visible exterior topersonal vaporizer unit 100.

PC-board 123 may have mounted on it a microprocessor, memory, or othercircuitry (not shown) to activate or otherwise control personalvaporizer unit 100. This microprocessor may store data about theoperation of personal vaporizer unit 100 in the memory. For example, themicroprocessor may determine and store the number of cycles personalvaporizer unit 100 has been triggered. The microprocessor may also storea time and/or date associated with one or more of these cycles. Themicroprocessor may cause this data to be output via a connector. Theconnector may be comprised of the first and second conductive surfacesof mouthpiece 116 and/or outer main shell 102.

In an embodiment, the microprocessor may determine a duration associatedwith various cycles where personal vaporizer unit 100 has beentriggered. These durations (or a number based on these durations, suchas an average) may be stored in the memory. The microprocessor may causethese numbers to be output via the connector. The microprocessor maydetermine an empty cartridge condition and store a number associatedwith a number of times said empty cartridge condition occurs. Themicroprocessor, or other circuitry, may determine an empty cartridgecondition based on a resistance between atomizer housing 132 or 232 anda wick 134, 234, 136, or 236. The microprocessor may also store a timeand/or date associated with one or more of these empty cartridgeconditions. The number of times an empty cartridge condition isdetected, times, and/or dates associated with these empty cartridgeconditions may be output via the connector.

Battery 104, PC-board 123, PC-board 124, and all electronics internal topersonal vaporizer unit 100 may be sealed in a plastic or plastic andepoxy compartment within the device. This compartment may include mainhousing 160 or 260. All penetrations in this compartment may be sealed.Thus, only wires will protrude from the compartment. The compartment maybe filled with epoxy after the assembly of battery 104, PC-board 123,PC-board 124, and LEDs 125-127. The compartment may be ultrasonicallywelded closed after assembly of battery 104, PC-board 123, PC-board 124,and LEDs 125-127. This sealed compartment is configured such that allvapor within personal vaporizer unit 100 does not come in contact withthe electronics on PC-boards 123, 124.

FIG. 35 is a perspective view of a proximal wick element of a personalvaporizer unit. FIG. 35 shows a proximal wick 136, internal wirepassageway 136-1 and external wire passageway 136-2. FIG. 35A is aperspective view of a heating element disposed through a proximal wickelement of a personal vaporizer unit. FIG. 35B is a perspective view ofa heating element of a personal vaporizer unit. FIG. 36 is a distal endview of the wick element of FIG. 35. FIG. 37 is a cross-section view ofthe wick element along the cut line shown in FIG. 35. Proximal wick 136is configured to fit within atomizer housing 132. As can be seen inFIGS. 35-37, proximal wick 136 includes internal wire passageway 136-1and external wire passageway 136-2. These wire passageways allow aconductor or a heating element 139 to be positioned through proximalwick 136 (via internal wire passageway 136-1). This conductor or heatingelement 139 may also be positioned in external wire passageway 136-2.Thus, as shown in FIG. 35A, a conductor or heating element 139 may bewrapped around a portion of proximal wick 136 by running the conductoror heating element 139 through internal wire passageway 136-1, aroundthe distal end of proximal wick 136, and through external wirepassageway 136-2 to return to approximately its point of origin. Theheating element 139 may, when personal vaporizer unit 100 is activated,heat proximal wick 136 in order to facilitate vaporization of asubstance.

FIG. 38 is a perspective view of a distal wick element of a personalvaporizer unit. FIG. 39 is a distal end view of the wick element of FIG.38. FIG. 40 is a cross-section view of the wick element along the cutline shown in FIG. 39. Distal wick 134 is configured to fit withinatomizer housing 132. As can be seen in FIGS. 38-40, distal wick 134comprises two cylinders of different diameters. A chamfered surfacetransitions from the smaller diameter of the distal end of distal wick134 to a larger diameter at the proximal end of distal wick 134. Thecylinder at the distal end terminates with a flat surface end 134-1.This flat surface end 134-1 is the end of distal wick 134 and is asurface that is placed in direct contact with a substance to bevaporized when cartridge 150 is inserted into the distal end of personalvaporizer unit 100. The proximal end of distal wick 134 is typically incontact with proximal wick 136. However, at least a part of proximalwick 136 and distal wick 134 are separated by an air gap. When distalwick 134 and proximal wick 136 are used together, this air gap is formedbetween distal wick 134 and proximal wick 136 by standoffs 136-3 asshown in FIG. 37.

FIG. 41 is a perspective view of a distal wick element of a personalvaporizer unit. FIG. 42 is a distal end view of the wick element of FIG.41. FIG. 43 is a cross-section view of the wick element along the cutline shown in FIG. 42. Distal wick 234 may be used as an alternativeembodiment to distal wick 134. Distal wick 234 is configured to fitwithin atomizer housing 232. As can be seen in FIGS. 41-43, distal wick234 comprises two cylinders of different diameters, and a cone orpointed end 234-1. A chamfered surface transitions from the smallerdiameter of the distal end of distal wick 234 to a larger diameter atthe proximal end of distal wick 234. The cylinder at the distal endterminates with a pointed end 234-1. This pointed end 234-1 is the endof distal wick 234 and is in direct contact with a substance to bevaporized. This pointed end 234-1 may also break a seal on cartridge 150to allow the substance to be vaporized to come in direct contact withdistal wick 234. The proximal end of distal wick 234 is typically incontact with proximal wick 136, 236. However, at least a part ofproximal wick 136, 236 and distal wick 234 are separated by an air gap.When distal wick 234 and proximal wick 136, 236 are used together, thisair gap is formed between distal wick 234 and proximal wick 136, 236 bystandoffs 136-3, 236-3 as shown in FIGS. 37, 59.

FIG. 44 is a perspective view of an atomizer housing of a personalvaporizer unit. FIG. 45 is a distal end view of the atomizer housing ofFIG. 44. FIG. 46 is a side view of the atomizer housing of FIG. 44. FIG.47 is a top view of the atomizer housing of FIG. 44. FIG. 48 is across-section view of the atomizer housing along the cut line shown inFIG. 46. Atomizer housing 132 is configured to fit within outer mainshell 102. As can be seen in FIGS. 44-48, atomizer housing 132 comprisesroughly two cylinders of different diameters. A chamfered surface 132-3transitions from the smaller diameter of the distal end of atomizerhousing 132 to a larger diameter at the proximal end 132-4 of atomizerhousing 132. The larger diameter at the proximal end 132-4 of atomizerhousing 132 is configured to be press fit into light pipe sleeve 140.The cylinder at the distal end terminates with a spade shaped tip 132-2.This spade shaped tip 132-2 may break a seal on cartridge 150 to allowthe substance to be vaporized to come in direct contact with distal wick134. Other shaped tips are possible (e.g., needle or spear shaped).

Chamfered surface 132-3 has one or more holes 132-1. These holes allowair to pass, via suction, through atomizer housing 132 into distal wick134. This suction may be supplied by the user of personal vaporizer unit100 sucking or inhaling on mouthpiece cover 114 and/or mouthpiece 116.The air that is sucked into distal wick 134 enters distal wick 134 on ornear the chamfered surface between the two cylinders of distal wick 134.The air that is sucked into distal wick 134 displaces some of thesubstance being vaporized that has been absorbed by distal wick 134causing it to be atomized as it exits distal wick 134 into the air gapformed between distal wick 134 and proximal wick 136. The heatingelement disposed around proximal wick 136 may then vaporize at leastsome of the atomized substance. In an embodiment, one or more holes132-1 may range in diameter between 0.02 and 0.0625 inches.

In an embodiment, placing holes 132-1 at the leading edge of thechamfered surface places a set volume of the substance to be vaporizedin the path of incoming air. This incoming air has nowhere to go butthrough the large diameter (or “head”) end of the distal wick 134. Whenthe air enters this area in distal wick 134 it displaces the substanceto be vaporized that is suspended in distal wick 134 towards an aircavity between distal wick 134 and proximal wick 136. When the displacedsubstance to be vaporized reaches the surface of distal wick 134, it isforced out of the wick by the incoming air and the negative pressure ofthe cavity. This produces an atomized cloud of the substance to bevaporized. In an embodiment, the diameter of the head end of the distalwick 134 may be varied and be smaller than the diameter of the proximalwick 136. This allows for a tuned volume of air to bypass proximal wick136 and directly enter the cavity between distal wick 134 and proximalwick 136 without first passing through proximal wick 136.

FIG. 49 is a perspective view of an atomizer housing of a personalvaporizer unit. FIG. 50 is a distal end view of the atomizer housing ofFIG. 49. FIG. 51 is a side view of the atomizer housing of FIG. 49. FIG.52 is a top view of the atomizer housing of FIG. 49. FIG. 53 is across-section view of the atomizer housing along the cut line shown inFIG. 52. Atomizer housing 232 is an alternative embodiment, for use withdistal wick 234, to atomizer housing 132. Atomizer housing 232 isconfigured to fit within outer main shell 102 and light pipe sleeve 140.As can be seen in FIGS. 49-53, atomizer housing 232 comprises roughlytwo cylinders of different diameters. A chamfered surface 232-3transitions from the smaller diameter of the distal end of atomizerhousing 232 to a larger diameter at the proximal end 232-4 of atomizerhousing 232. The larger diameter at the proximal end 232-4 of atomizerhousing 232 is configured to be press fit into light pipe sleeve 140.The cylinder at the distal end terminates with an open cylinder tip232-2. This open cylinder tip 232-2 allows the pointed end 234-1 ofdistal wick 234 to break a seal on cartridge 150 to allow the substanceto be vaporized to come in direct contact with distal wick 234.

Chamfered surface 232-3 has one or more holes 232-1. These holes allowair to pass, via suction, through atomizer housing 232 into distal wick234. The air that is sucked into distal wick 234 enters distal wick 234on or near the chamfered surface between the two cylinders of distalwick 234. The air that is sucked into distal wick 234 displaces some ofthe substance being vaporized that has been absorbed by distal wick 234causing it to be atomized as it exits distal wick 234 into the air gapformed between distal wick 234 and proximal wick 136. The heatingelement disposed around proximal wick 136 may then vaporize at leastsome of the atomized substance being vaporized. In an embodiment, one ormore holes 232-1 may range in diameter between 0.02 and 0.0625 inches.

In an embodiment, placing holes 232-1 at the leading edge of thechamfered surface places a set volume of the substance to be vaporizedin the path of incoming air. This incoming air has nowhere to go butthrough the head end of the distal wick 234. When the air enters thisarea in distal wick 234 it displaces the substance to be vaporized thatis suspended in distal wick 234 towards an air cavity between distalwick 234 and proximal wick 236. When the displaced substance to bevaporized reaches the surface of distal wick 234, it is forced out ofthe wick by the incoming air and the negative pressure of the cavity.This produces an atomized cloud of the substance to be vaporized. In anembodiment, the diameter of the head end of distal wick 234 may bevaried and be smaller than the diameter of the proximal wick 236. Thisallows for a tuned volume of air to bypass proximal wick 236 anddirectly enter the cavity between distal wick 234 and proximal wick 236without first passing through proximal wick 236.

FIG. 54 is a perspective view of an atomizer housing and wicks of apersonal vaporizer unit. FIG. 55 is an exploded view of the atomizerhousing, wire guides, and wicks of FIG. 54. FIG. 56 is a side view ofthe atomizer housing and wicks of FIG. 54. FIG. 57 is a distal end viewof the atomizer housing and wicks of FIG. 54. FIG. 58 is a cross-sectionview of the atomizer housing and wicks along the cut line shown in FIG.57. The atomizer housing and wicks shown in FIGS. 54-58 is analternative embodiment for use with proximal wick 236. The embodimentshown in FIGS. 54-58 use atomizer housing 232, distal wick 234, proximalwick 236, wire guide 237, and wire guide 238. Proximal wick 236 isconfigured to fit within atomizer housing 232. As can be seen in FIGS.54-58, proximal wick 236 includes internal wire passageway 236-1. Thiswire passageway 236-1 allows a conductor or a heating element (notshown) to be positioned through proximal wick 236 (via internal wirepassageway 236-1). The conductor or heating element may be positionedaround wire guide 237 and wire guide 238. Thus, a conductor or heatingelement may run through wire passageway 236-1, around wire guides 237and 238, and then back through wire passageway 236-1 to return toapproximately its point of origin. The heating element may, whenpersonal vaporizer unit 100 is activated, heat proximal wick 236 inorder to facilitate vaporization of a substance.

FIG. 59 is a perspective view of the proximal wick assembly of FIGS.54-58. FIG. 59A is a perspective view showing a heating element disposedthrough the proximal wick and around the wire guides of FIGS. 54-58.FIG. 59B is a perspective view of the heating element of a personalvaporizer unit. FIG. 60 is a distal end view of the proximal wickelement and wire guides of FIGS. 54-58. FIG. 61 is a cross-section viewof the proximal wick element and wire guides along the cut line shown inFIG. 60. As can be seen in FIG. 59A, a conductor or heating element 239may run through internal wire passageway 236-1, around wire guides 237and 238, and then back through internal wire passageway 236-1 to returnto approximately its point of origin.

In an embodiment, distal wicks 134, 234, and proximal wicks 136, 236,may be made of, or comprise, for example a porous ceramic. Distal wicks134, 234, and proximal wicks 136, 236, may be made of, or comprisealuminum oxide, silicon carbide, magnesia partial stabilized zirconia,yttria tetragonal zirconia polycrystal, porous metal (e.g., steel,aluminum, platinum, titanium, and the like), ceramic coated porousmetal, woven metal, spun metal, metal wool (e.g., steel wool), porouspolymer, porous coated polymer, porous silica (i.e., glass), and/orporous Pyrex. Distal wicks 134, 234, and proximal wicks 136, 236, may bemade of or comprise other materials that can absorb a substance to bevaporized.

The conductor or heating element that is disposed through proximal wick136 or 236 may be made of, or comprise, for example: nickel chromium,iron chromium aluminum, stainless steel, gold, platinum, tungstenmolybdenum, or a piezoelectric material. The conductor or heatingelement that is disposed through proximal wick 136 or 236 can be madeof, or comprise, other materials that become heated when an electricalcurrent is passed through them.

FIG. 62 is a perspective view of a light pipe sleeve of a personalvaporizer unit. FIG. 63 is an end view of the light pipe sleeve of FIG.62. FIG. 64 is a cross-section view of the light pipe sleeve along thecut line shown in FIG. 63. Light pipe sleeve 140 is configured to bedisposed within outer main shell 102. Light pipe sleeve 140 is alsoconfigured to hold cartridge 150 and atomizer housing 132 or 232. Asdiscussed previously, light pipe sleeve 140 is configured to conductlight entering the proximal end of light pipe sleeve 140 (e.g., fromLEDs 125-127) to the distal end of light pipe sleeve 140. Typically, thelight exiting the distal end of light pipe sleeve 140 will be visiblefrom the exterior of personal vaporizer unit 100. The light exiting thedistal end of light pipe sleeve 140 may be diffused by cartridge 150.The light exiting the distal end of light pipe sleeve 140 may illuminatecharacters and/or symbols drawn, printed, written, or embossed, etc., inan end of cartridge 150. In an embodiment, light exiting light pipesleeve 140 may illuminate a logo, characters and/or symbols cut throughouter main shell 102. In an embodiment, light pipe sleeve 140 is madeof, or comprises, a translucent acrylic plastic.

FIG. 65 is a perspective view of a cartridge of a personal vaporizerunit. FIG. 66 is a proximal end view of the cartridge of FIG. 65. FIG.67 is a side view of the cartridge of FIG. 65. FIG. 68 is a top view ofthe cartridge of FIG. 65. FIG. 69 is a cross-section view of thecartridge along the cut line shown in FIG. 66. As shown in FIGS. 65-69,cartridge 150 comprises a hollow cylinder section with at least oneexterior flat surface 158. The flat surface 158 forms, when cartridge150 is inserted into the distal end of personal vaporizer unit 100, anopen space between the exterior surface of the cartridge and an interiorsurface of light pipe sleeve 140. This space defines a passage for airto be drawn from outside personal vaporizer unit 100, through personalvaporizer unit 100 to be inhaled by the user along with the vaporizedsubstance. This space also helps define the volume of air drawn intopersonal vaporizer unit 100. By defining the volume of air typicallydrawn into the unit, different mixtures of vaporized substance to airmay be produced.

The hollow portion of cartridge 150 is configured as a reservoir to holdthe substance to be vaporized by personal vaporizer unit 100. The hollowportion of cartridge 150 holds the substance to be vaporized in directcontact with distal wick 134 or 234. This allows distal wick 134 or 234to become saturated with the substance to be vaporized. The area ofdistal wick 134 or 234 that is in direct contact with the substance tobe vaporized may be varied in order to deliver different doses of thesubstance to be vaporized. For example, cartridges 150 with differingdiameter hollow portions may be used to deliver different doses of thesubstance to be vaporized to the user.

Cartridge 150 may be configured to confine the substance to be vaporizedby a cap or seal (not shown) on the proximal end. This cap or seal maybe punctured by the end of atomizer housing 132, or the pointed end234-1 of distal wick 234.

When inserted into personal vaporizer unit 100, cartridge standoffs 157define an air passage between the end of light pipe sleeve 140 and outermain shell 102. This air passage allows air to reach the air passagedefined by flat surface 158.

The hollow portion of cartridge 150 also includes one or more channels154. The end of these channels are exposed to air received via the airpassage(s) defined by flat surface 158. These channels allow air toenter the hollow portion of cartridge 150 as the substance contained incartridge 150 is drawn into a distal wick 134 or 234. Allowing air toenter the hollow portion of cartridge 150 as the substance contained incartridge 150 is removed prevents a vacuum from forming inside cartridge150. This vacuum could prevent the substance contained in cartridge 150from being absorbed into distal wick 134 or 234.

In an embodiment, cartridge 150 may be at least partly translucent. Thuscartridge 150 may act as a light diffuser so that light emitted by oneor more of LEDs 125-127 is visible external to personal vaporizer unit100.

FIG. 70 is a side view of a battery of a personal vaporizer unit. FIG.71 is an end view of the battery of FIG. 70. FIG. 72 is a perspectiveview of a battery support of a personal vaporizer unit. As can be seenin FIG. 72, battery support 106 does not form a complete cylinder thatcompletely surrounds battery 104. This missing portion of a cylinderforms a passageway that allows air and the vaporized substance to passby the battery from the atomizer assembly to the mouthpiece 116 so thatit may be inhaled by the user.

FIG. 73 is a top perspective view of a personal vaporizer unit case.FIG. 74 is a bottom perspective view of a personal vaporizer unit case.Personal vaporizer case 500 is configured to hold one or more personalvaporizer units 100. Personal vaporizer case 500 includes a connector510 to interface to a computer. This connector allows case 500 totransfer data from personal vaporizer unit 100 to a computer viaconnector 510. Case 500 may also transfer data from personal vaporizerunit 100 via a wireless interface. This wireless interface may comprisean infrared (IR) transmitter, a Bluetooth interface, an 802.11 specifiedinterface, and/or communicate with a cellular telephone network. Datafrom a personal vaporizer unit 100 may be associated with anidentification number stored by personal vaporizer unit 100. Data frompersonal vaporizer unit 100 may be transmitted via the wirelessinterface in association with the identification number.

Personal vaporizer case 500 includes a battery that may hold charge thatis used to recharge a personal vaporizer unit 100. Recharging ofpersonal vaporizer unit 100 may be managed by a charge controller thatis part of case 500.

When case 500 is holding a personal vaporizer unit 100, at least aportion of the personal vaporizer unit 100 is visible from the outsideof case 500 to allow a light emitted by personal vaporizer unit 100 toprovide a visual indication of a state of personal vaporizer unit 100.This visual indication is visible outside of case 500.

Personal vaporizer unit 100 is activated by a change in impedancebetween two conductive surfaces. In an embodiment, these two conductivesurfaces are part of outer main shell 102 and mouthpiece 116. These twoconductive surfaces may also be used by case 500 to charge battery 104.These two conductive surfaces may also be used by case 500 to read dataout of personal vaporizer unit 100.

In an embodiment, when a user puts personal vaporizer unit 100 inhis/her mouth and provides “suction,” air is drawn into personalvaporizer unit 100 though a gap between the end of outer main shell 102and cartridge 150. In an embodiment, this gap is established bystandoffs 157. Air travels down galley(s) formed by flat surface(s) 158and the inner surface of light pipe sleeve 140. The air then reaches a“ring” shaped galley between atomizer housing 132, cartridge 150, andlight pipe sleeve 140. Air travels to distal wick 134 via one or moreholes 132-1, in chamfered surface(s) 132-3. Air travels to distal wick234 via one or more holes 232-1, in chamfered surface(s) 232-3. Air isalso allowed to enter cartridge 150 via one or more channels 154. Thisair entering cartridge 150 via channels 154 “back fills” for thesubstance being vaporized which enters distal wick 134. The substancebeing vaporized is held in direct contact with distal wick 134 or 234 bycartridge 150. The substance being vaporized is absorbed by and maysaturate distal wick 134 or 234 and proximal wick 136 or 236.

The incoming air drawn through holes 132-1 displaces from saturateddistal wick 134 the substance being vaporized. The displaced substancebeing vaporized is pulled from distal wick element 134 into a cavitybetween distal wick 134 and proximal wick 136. This cavity may alsocontain a heating element that has been heated to between 150-200° C.The displaced substance being vaporized is pulled from distal wickelement 134 in small (e.g., atomized) droplets. These atomized dropletsare vaporized by the heating element.

In an embodiment, when a user puts personal vaporizer unit 100 inhis/her mouth and provides “suction,” air is drawn into personalvaporizer unit 100 though a gap between the end of outer main shell 102and cartridge 150. In an embodiment, this gap is established bystandoffs 157. Air travels down galley(s) formed by flat surface(s) 158and the inner surface of light pipe sleeve 140. The air then reaches a“ring” shaped galley between atomizer housing 232, cartridge 150, andlight pipe sleeve 140. Air travels to distal wick 234 via one or moreholes 232-1, in chamfered surface(s) 232-3. Air is also allowed to entercartridge 150 via one or more channels 154. This air entering cartridge150 via channels 154 “back fills” for the substance being vaporizedwhich enters distal wick 234. The substance being vaporized is held indirect contact with distal wick 234 by cartridge 150. The substancebeing vaporized is absorbed by and may saturate distal wick 234 andproximal wick 236.

The incoming air drawn through holes 232-1 displaces from saturateddistal wick 234 the substance being vaporized. The displaced substancebeing vaporized is pulled from distal wick 234 into a cavity betweendistal wick 234 and proximal wick 236.
